The SWIRL-3 propeller range is the 1st propeller fully developed by simulation.
The shape has been defined and maximized with a lot aerodynamic simulation in CFDs under ANSYS Fluent.
These propellers deliver high efficiency over the entire flight envelope, particulary optimized for cruising i.e.:
High “Constant sped” effect and High Calculated Efficiencies
Low fuel consumption and Low noise
A high user comfort
Equipped with grade 5 titanium hardware, this technology and manufacturing level and requirement degree have never been to this advancement. Their variable pitch carbon hub system allows a wide range of angle variation, while being secured by an innovative self-locking step system.
The setting of the pitch angle of the blades is "Constant Speed", in other words managed automatically by a hydraulic governor which regulates the propeller pitch according to its engine speed setting.
The pitch variation is done by the hydraulic power and the governor adjustment control is simply mechanical (pusher or lever). No electric current is consumed for this type of hydraulic variable pitch propeller.
